The Multi-Function Valve is an accessory to the Walchem family of metering pumps. It is specifically designed to be mounted and used with the EH and EZ electronic metering pumps.
The Multi-Function Valve combines the air vent and bleed capabilities of the manual air vent valve with anti-siphon, back pressure, and pressure release functions.
It is easily mounted onto the pump by removing the standard manual air vent valve and replacing it with the MFV. No tools are necessary.
